Anaerobic Membrane Bioreactor

AnMBR is ideal for the treatment of wastewater streams with high concentrations of organics, solids, fat, oil, and grease. Ultrafiltration membranes (UF) ensure complete solids retention, efficient system operation and process stability in the anaerobic systems at all times. The AnMBR biomass has a different consistency compared to the aerobic MBR and contains more single cells.

Membrane fouling is mainly caused by deposits and accumulation of micro-organisms, colloids, solutes and cell debris on the membrane surface. Therefore, the main challenge in this process is to control fouling potential via low-fouling membranes, optimal operational conditions and advanced cleaning protocols.

Traditional anaerobic systems can be easily upgraded to an AnMBR configuration in order to increase loading capacity, and improve performance and effluent quality.

Industrial wastewater with high organic loads is a potential and valuable source of energy if treated anaerobically.

Anaerobic membrane bioreactor (AnMBR) systems combine anaerobic digestion with physical separation via membrane filtration, resulting in maximum organic load removal. Additionally, the methane rich in biogas can be used as a renewable source of power or heat.
